SPECIFICATION forming part of Letters Patent No. 545,435, dated August27, 1895.

Application filed May 12, 18 9 Serial No. 511,063. (No model.)

To all whom it mag concern:

Be it known that 1, JAMES H. DALY, a citi zen of the United States,residing at Detroit, in the county of Wayne, State of Michigan,

have invented certain new and useful Improvements in Gar-Couplers; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itapro pertains to make and use the same, reference beinghad to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to certain new and r5 useful improvements incar-couplers; and it consists in the construction and arrangement ofparts, as hereinafter fully set forth, and pointed out particularly inthe claims.

The object of the invention is to produce a 20 coupler of simple anddurable construction, in which provision is made for automaticallycoupling the cars by the meeting of the drawheads without previoussetting of the jaws or hooks, and in which the arrangement is such as toenable the coupling-hook to be reversed, so that the engaging-pointthereof may be made to stand in either of two opposite directions. Thisobject is attained by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a plan view showing the drawheadscoupled. Fig. 2 is a central horizontal section through the draw-bar.Fig. 3 is a perspective of the coupling-hook. Fig. at is a cen- 3 5 tralvertical section through the draw-bar in position as at right of Fig.1'. Fig. 5 is a transverse section on line 5 5 of Fig. 1.

Referring to the letters of reference, A designates the drawbar, whichis hollow and pro- 0 vidcd with the head 13, having a recessed mouthformed by the curved side extensions 1) and b, which are adapted toembrace companion parts on the opposite head.

0 designates the coupling-hook, which is pivoted centrally within thedraw-head by means of the pin C6 passing through said head and hook. Theforward end of said hook curves laterally and lies partially within therecess of the head on one side, the en gagingpoint e extendinginto themouth in line with the pivotal point of the hook,

thereby placdepending from the under ing the draft upon said hookdirectly in line with the center of the draw-bar. The rear end of thehook O is provided with a flaring slot e, having an enlargedtermination. In this slot is loosely received the free forward end ofthe straight spring D, the rear end of which is secured by means of thepin 6' contrally within a block D in the draw-bar. The end of saidspring does not extend to the limit of the slote, whereby it is relievedfrom buckling by any concussion against the end of the hook, and thetension of the spring, while permitting the hook to swing in eitherdirection, will return to its normal or central position when said hookis released. The hooks are so mounted in the opposed drawheads that whensaid heads are brought together the rounded endsi thereof will engageand force said hooks back into the recess of the heads until theengaging-points thereof shall have passed one another, when the springsD will force said hook together and automatically couple the cars, asshown in Fig. 1, in which the position of the parts is such as to permitof a free oscillation of the drawheads to accommodate themselves to theposition of the cars when rounding a curve and at the same timemaintaining a straight pull upon the draw-bars.

To actuate the hooks C for the purpose of uncoupling them there isemployed an elbowlever E, which is pivoted between the studs at,

face of the drawhead through an opening in which the one end of saidlever extends and engages in a slot 0' in the face of the hook forwardof its'point of pivot, by which arrangement the actuation of the outerend of the leverE will cause a lateral movement of the engaging end ofthe hook to disengage it from the hook in the opposite head and uncouplethe cars.

It is desirable in couplers of this class that the coupling-hook shallbe reversible to enable it to be changed, so as to couple with adraw-head in which the hook stands in the opposite direction from thosecommonly in use. This I accomplish by providing the opposite horizontalface of the hook with a way 0, leading outward from the slot 0 in linetherewith, and in making the pin a removable, so that by removing saidpin the hook maybe withdrawn from the draw-head, reversed,and replacedtherein, as shown by dotted lines in Fig. 2, the way in the hookpermitting its removal and replacing without removing the lever E, theend of which isreceived in said way, and which also serves to actuatesaid hook when reversed as well as when in its normal position Toprovide for relieving the pin a from the {0 thrust caused by the meetingof the hooks in coupling, shoulders s are formed on opposite sides ofthe hook in the rear of the aperture h therein which receives said pin,which said shoulders abut against diametrically-extendr5 ing lugs 15,projecting from the inner opposite walls of the draw-bar, as shown moreclearly in Fig. 4, and which serve to resist the thrust against saidhook.

The engaging-face of the hooks is increased vertically by means of theshoulders c, which extend beyond the plane of the faces of the hooks inline with the outer faces of the drawheads, thereby insuring anengagement of the hooks even where there is an unusual variation in theheight of the cars. In the outer ends of the hooks is a recess 0, andpassing vertically through the hook and reccss is an aperture 1; for thereception of a pin, whereby provision is made for coupling 0 with theordinary link and pin.

This coupler is made to operate from the side of the car by means of arod crossingthe end of the car and coupled in any suitable manner withthe lever E, to enable the cars to 5 be uncoupled without enteringbetween them. Having thus fully set forth my invention,

what I claim as new, and desire to secure by l Letters Patent, is

1. In a car-coupler, the combination of the draw-head, the hook pivotedcentrally therein upon a removable pin, said hook having a Way in itsopposite horizontal faces extending horizontally thereof across itspoint of pivot, the elbow lever pivoted in said head and engaging in theway in the under-most side of said hook in the rear of the pivotthereof, whereby said hook is made reversible in the draw-head.

2. In a car-coupler, the combination of the draw-head, the hook pivotedcentrally therein, the shoulder on said hook concentric with its pointof pivot lying within the draw-head, and the lug on the inner face ofthe draw head engaging said shoulder.

3. In a car coupler, the combination of the draw-head having a recess inone side of the mouth thereof, the hook pivoted in said mouth andadapted to swinginto said recess, the point or engaging end of said hookhaving the ver ticallyextending shoulders which project into line withthe horizontal faces of said drawhead on each side of said recess.

4. In a car-coupler, the combination of the draw-head, the hook pivotedtherein, said hook having a curved shoulder extending pan tially aroundits point of pivot concentric therewith and having alongitudinal way inits face crossing said point of pivot and opening through said shoulder,the elbow lever pivoted in the draw-head one end of which engages insaid way in the hook, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
